====================
sctp: add another two stream schedulers
All SCTP stream schedulers are defined in rfc8260#section-3,
First-Come First-Served, Round-Robin and Priority-Based
Schedulers are already added in kernel.
This patchset adds another two schedulers: Fair Capacity
Scheduler and Weighted Fair Queueing Scheduler.
Note that the left one "Round-Robin Scheduler per Packet"
Scheduler is not implemented by this patch, as it's still
intrusive to be added in the current SCTP kernel code.

As it says in rfc8260#section-3.6 about the weighted fair queueing
scheduler:
A Weighted Fair Queueing scheduler between the streams is used. The
weight is configurable per outgoing SCTP stream. This scheduler
considers the lengths of the messages of each stream and schedules
them in a specific way to use the capacity according to the given
weights. If the weight of stream S1 is n times the weight of stream
S2, the scheduler should assign to stream S1 n times the capacity it
assigns to stream S2. The details are implementation dependent.
Interleaving user messages allows for a better realization of the
capacity usage according to the given weights.
This patch adds Weighted Fair Queueing Scheduler actually based on
the code of Fair Capacity Scheduler by adding fc_weight into struct
sctp_stream_out_ext and taking it into account when sorting stream->
fc_list in sctp_sched_fc_sched() and sctp_sched_fc_dequeue_done().

As it says in rfc8260#section-3.5 about the fair capacity scheduler:
A fair capacity distribution between the streams is used. This
scheduler considers the lengths of the messages of each stream and
schedules them in a specific way to maintain an equal capacity for
all streams. The details are implementation dependent. interleaving
user messages allows for a better realization of the fair capacity
usage.
This patch adds Fair Capacity Scheduler based on the foundations added
by commit 5bbbbe32a431 ("sctp: introduce stream scheduler foundations"):
A fc_list and a fc_length are added into struct sctp_stream_out_ext and
a fc_list is added into struct sctp_stream. In .enqueue, when there are
chunks enqueued into a stream, this stream will be linked into stream->
fc_list by its fc_list ordered by its fc_length. In .dequeue, it always
picks up the 1st skb from stream->fc_list. In .dequeue_done, fc_length
is increased by chunk's len and update its location in stream->fc_list
according to the its new fc_length.
Note that when the new fc_length overflows in .dequeue_done, instead of
resetting all fc_lengths to 0, we only reduced them by U32_MAX / 4 to
avoid a moment of imbalance in the scheduling, as Marcelo suggested.

Now that the same hardware that the r8188eu driver supported is
supported by the real wireless driver rtl8xxxu, the r8188eu driver can
be deleted.
Also the rtl8xxxu driver supports way more devices, and is a fraction of
the overall size, making this a much better overall solution.
Thanks to the r8188eu developers and maintainers and reviewers over the
years, your work allowed Linux users to use their hardware before the
real driver was implemented properly.

====================
Various mtk_eth_soc cleanups
Here are a number of patches that do a bit of cleanup to mtk_eth_soc.
The first patch cleans up mtk_gmac0_rgmii_adjust(), which is the
troublesome function preventing the driver becoming a post-March2020
phylink driver. It doesn't solve that problem, merely makes the code
easier to follow by getting rid of repeated tenary operators.
The second patch moves the check for DDR2 memory to the initialisation
of phylink's supported_interfaces - if TRGMII is not possible for some
reason, we should not be erroring out in phylink MAC operations when
that can be determined prior to phylink creation.
The third patch removes checks from mtk_mac_config() that are done
when initialising supported_interfaces - phylink will not call
mtk_mac_config() with an interface that was not marked as supported,
so these checks are redundant.
The last patch removes the remaining vestiges of REVMII and RMII
support, which appears to be entirely unused.
These shouldn't conflict with Daniel's patch set, but if they do I
will rework as appropriate.

Since the conversion of mtk_eth_soc to phylink's supported_interfaces
bitmap, these two modes have not been selectable. No one has raised
this as an issue. Checking the in-kernel DT files, none of them use
either of these modes with this hardware.
Daniel Golle concurs:
A quick grep through the device trees of the more than 650 ramips and
mediatek boards we support in OpenWrt has revealed that *none* of them
uses either reduced-MII or reverse-MII PHY modes. I could imaging that
some more specialized ramips boards may use the RMII 100M PHY mode to
connect with exotic PHYs for industrial or automotive applications
(think: for 100BASE-T1 PHY connected via RMII). I have never seen or
touched such boards, but there are hints that they do exist.
For reverse-MII there are cases in which the Ralink SoC (Rt305x, for
example) is used in iNIC mode, ie. connected as a PHY to another SoC,
and running only a minimal firmware rather than running Linux. Due to
the lack of external DRAM for the Ralink SoC on this kind of boards,
the Ralink SoC there will anyway never be able to boot Linux.
I've seen this e.g. in multimedia devices like early WiFi-connected
not-yet-so-smart TVs.
Consequently, the conclusion is that no one uses these modes with this
hardware, so we might as well drop support for them.

mtk_mac_config() checks that the interface mode is permitted for the
capabilities, but we already do these checks in mtk_add_mac() when
initialising phylink's supported_interfaces bitmap. Remove the

If TRGMII mode is not permitted when using DDR2 mode, we should handle
that when setting up phylink's ->supported_interfaces so phylink knows
that this is not supported by the hardware. Move this check to
mtk_add_mac().

PCI/AER: Remove redundant Device Control Error Reporting Enable
From: Bjorn Helgaas <bhelgaas@google.com>
Since f26e58bf6f54 ("PCI/AER: Enable error reporting when AER is native"),
which appeared in v6.0, the PCI core has enabled PCIe error reporting for
all devices during enumeration.
Remove driver code to do this and remove unnecessary includes of
<linux/aer.h> from several other drivers.
Intel folks, sorry that I missed removing the <linux/aer.h> includes in the
first series.

Messages. Since f26e58bf6f54 ("PCI/AER: Enable error reporting when AER is
native"), the PCI core does this for all devices during enumeration, so the

Remove the redundant pci_enable_pcie_error_reporting() call from the

cd709aa90648 ("bnx2: Add PCI Advanced Error Reporting support.") added
pci_enable_pcie_error_reporting() for all devices, and c239f279e571 ("bnx2:
Enable AER on PCIE devices only") restricted it to BNX2_CHIP_5709 devices
to avoid an error message when it failed on non-PCIe devices. The PCI core
only enables PCIe error reporting on PCIe devices, which I assume means
BNX2_CHIP_5709.

Lorenzo points out that the generic CLI is broken for the netdev
family. When I added the support for documentation of enums
(and sparse enums) the client script was not updated.
It expects the values in enum to be a list of names,
now it can also be a dict (YAML object).

When sock_alloc_file fails to allocate a file, it will call sock_release.
__sys_socket_file should then not call sock_release again, otherwise there

syzbot reported struct pid leak [1].
Issue is that queue_oob() calls maybe_add_creds() which potentially
holds a reference on a pid.
But skb->destructor is not set (either directly or by calling
unix_scm_to_skb())
This means that subsequent kfree_skb() or consume_skb() would leak
this reference.
In this fix, I chose to fully support scm even for the OOB message.

R-Car H3 ES1.* was only available to an internal development group and
needed a lot of quirks and workarounds. These become a maintenance
burden now, so our development group decided to remove upstream support
and disable booting for this SoC. Public users only have ES2 onwards.

The MT7530 switch from the MT7621 SoC has 2 ports which can be set up as
internal: port 5 and 6. Arınç reports that the GMAC1 attached to port 5
receives corrupted frames, unless port 6 (attached to GMAC0) has been
brought up by the driver. This is true regardless of whether port 5 is
used as a user port or as a CPU port (carrying DSA tags).
Offline debugging (blind for me) which began in the linked thread showed
experimentally that the configuration done by the driver for port 6
contains a step which is needed by port 5 as well - the write to
CORE_GSWPLL_GRP2 (note that I've no idea as to what it does, apart from
the comment "Set core clock into 500Mhz"). Prints put by Arınç show that
the reset value of CORE_GSWPLL_GRP2 is RG_GSWPLL_POSDIV_500M(1) |
RG_GSWPLL_FBKDIV_500M(40) (0x128), both on the MCM MT7530 from the
MT7621 SoC, as well as on the standalone MT7530 from MT7623NI Bananapi
BPI-R2. Apparently, port 5 on the standalone MT7530 can work under both
values of the register, while on the MT7621 SoC it cannot.
The call path that triggers the register write is:
mt753x_phylink_mac_config() for port 6
-> mt753x_pad_setup()
-> mt7530_pad_clk_setup()
so this fully explains the behavior noticed by Arınç, that bringing port
6 up is necessary.
The simplest fix for the problem is to extract the register writes which
are needed for both port 5 and 6 into a common mt7530_pll_setup()
function, which is called at mt7530_setup() time, immediately after
switch reset. We can argue that this mirrors the code layout introduced
in mt7531_setup() by commit 42bc4fafe359 ("net: mt7531: only do PLL once
after the reset"), in that the PLL setup has the exact same positioning,
and further work to consolidate the separate setup() functions is not
hindered.
Testing confirms that:
- the slight reordering of writes to MT7530_P6ECR and to
CORE_GSWPLL_GRP1 / CORE_GSWPLL_GRP2 introduced by this change does not
appear to cause problems for the operation of port 6 on MT7621 and on
MT7623 (where port 5 also always worked)
- packets sent through port 5 are not corrupted anymore, regardless of
whether port 6 is enabled by phylink or not (or even present in the
device tree)
My algorithm for determining the Fixes: tag is as follows. Testing shows
that some logic from mt7530_pad_clk_setup() is needed even for port 5.
Prior to commit ca366d6c889b ("net: dsa: mt7530: Convert to PHYLINK
API"), a call did exist for all phy_is_pseudo_fixed_link() ports - so
port 5 included. That commit replaced it with a temporary "Port 5 is not
supported!" comment, and the following commit 38f790a80560 ("net: dsa:
mt7530: Add support for port 5") replaced that comment with a
configuration procedure in mt7530_setup_port5() which was insufficient
for port 5 to work. I'm laying the blame on the patch that claimed
support for port 5, although one would have also needed the change from
commit c3b8e07909db ("net: dsa: mt7530: setup core clock even in TRGMII
mode") for the write to be performed completely independently from port
6's configuration.
Thanks go to Arınç for describing the problem, for debugging and for
testing.
